The goal is to achieve the maximal radiotherapy tumor dose while sparing the health tissue and critical structures. On-board cone-beam CT (CBCT) scans are routinely acquired prior to dose delivery and matched with simulation CT at the planned treatment positions. Thus, setup or motion errors can be detected and corrected. However, CBCT is not available for situations with gantry collisions such as WBI and TSEB. More importantly, CBCT cannot reveal any irregular respiration or body movement during beam-on time. Thus, it is essential to develop a real-time image system that can detect organ/body motion during beam-on time, and correlate simulation-planning images with prior treatment CBCT images.In this proposed clinical trial, we will cooperate with a 3D camera company (Xigen LLC) to develop novel 4D video imaging techniques and validate the feasibility and accuracy of 4D video image guidance in correlation with 4D CT/CBCT useful for advanced IGRT.
